Yep, a gorgeous looking lens. Thanks!
On filter threads, that makes sense. My Nikkor-H Auto 85mm f1.8 lens has a 52mm filter thread.
85 / 1.8 = 47.2mm aperture
58 / 1.2 = 48.3mm aperture

Gorgeous indeed. One 'trick' that this lens shares with the current Voigtlander 58/1.4 is the extra 8mm over a typical 50mm lens. This extra length reduces the depth of field at a given aperture equivalent to ~1/2 stop. So, this lens is an f/1.0 lens in "50mm terms" (DOF but not light-gathering) but with more moderate size...
